type

A high-level characterization of the artifact, e.g. "maven-plugin" or "test-jar".
*
language
*
The programming language this artifact is relevant for, e.g. "java" or "none".
*
includesDependencies
*
A boolean flag indicating whether the artifact presents some kind of bundle that physically includes its
* dependencies, e.g. a fat WAR.
*
constitutesBuildPath
*
A boolean flag indicating whether the artifact is meant to be used for the compile/runtime/test build path of
* a consumer project.
*
localPath
*
The (expected) path to the artifact on the local filesystem. An artifact which has this property set is
* assumed to be not present in any regular repository and likewise has no artifact descriptor.
